BURLINGTON - Two brothers in Vermont have pleaded guilty in federal court in Burlington to felony heroin trafficking charges.

In return for their pleas, prosecutors have agreed to drop a conspiracy charge against Louis Prue II of Newport and Matthew Prue of Barton.

The Caledonian Record reported that the two men face potential 20-year prison terms and are scheduled to be sentenced March 10.

A police affidavit says an informant purchased an ounce of heroin from Louis Prue at a park-and-ride lot in Orleans on July 10 after buying a gram of heroin from Matthew Prue a day earlier. Both transactions were arranged via telephone calls monitored by police.

The Prues said in an affidavit they had been selling heroin in the area.
